flow in tube with heat transfer
i tried for long time to simulate a case of graetz flow.
it simply flow inside circular tube with fixed temperature at external wall different from flow temp. there is also a problem with velocity distribution of flow and temp. distribution.
solver is chtMultiRegionSimpleFoam.
case is attached in this link.
thanks in advance.
By the way, proof of the expected solution would also be helpful, so that you can prove that there is a problem with the solution you are getting! ;)
thanks for your reply, i attached all case because i didn't know where the problem and i spent a lot of time trying solving it. i searched a lot but didn't find similar case although i think this case is common.now my problem is finally solved and i will create a blog for it.
thanks for your interest.
